悬挂点

Farm implements can be attached to the rear of the tractor by either a drawbar or by a three-point hitch .

应用农机具通过挂钩或三点式悬挂机构连接在拖拉机上，三点式悬挂机构是由亨利。

"The Su-27 Flanker can carry up to 4 tons of various types of armament on 10 hardpoints, in our mission today we will be using AAM with both short and medium range."

Su-27可以在十个悬挂点下装载四吨重的各式各样的武器。在本训练任务中我们将使用近距和中距空对空导弹。

In addition, the method of Newmark is used to simulate and numerate the vibration characteristics of the rigid suspension of overhead contact system and to compare the dynamic vibration characteristics at different speeds and different spans.

利用Newmark方法对刚性悬挂的振动特性进行了数值计算和仿真模拟，比较了不同速度，不同吊点间距下接触网刚性悬挂的振动特性。

Firstly,the coordinates of suspension points on the side rope sling can be obtained in two-dimensional plane by the suspended-cable equations,and their ordinates are corrected by the moment equations,then the lengths of antenna wire segments are determined.

在二维平面内应用悬垂线方程式计算边吊索上各悬挂点的坐标，应用力矩公式修正以上计算结果，确定各振子线的长度。

Most of these parameters are relate to distance of tower,arc weight,ice-load,wind-load and admissible pulling force at suspension point.

这些特性参数中的大多数都与杆塔距离、弧重要求、冰荷、风荷和悬挂点的允许拉力有关。

Ceiling suspension point: Each suspension point is allowed to hang light advertisement carrier of below 10 kg.

天花吊挂点：每个挂点只允许悬挂10公斤以下的轻质广告载体。

Simple physics: A static object's center of gravity must be directly above or below the point of suspension, otherwise the object will fall.

简单的物理学：一个静止的物体，其重心一定位于其悬挂点的正上或正下方，否则物体就会倒。

The lift course of hanging device on wheat no-tillage planter was simulated by using the software of ADAMS. Some important parameters were obtained such as height of the working part relative to ground, the distance between the working part and the rear wheel of tractor, the angle of road pass and the force of hanging point, etc. The key parameters of the hanging device and its best working parameter of hanging device were found out through optimization simulation. Simulation results showed that suspension point had minimum force when variable DV_1 and DV_2 gained corresponding maximum and minimum at scope of structure limit.

应用ADAMS软件对小麦免耕播种机悬挂机构提升过程进行了动态仿真，得到了工作部件的位置高度、工作部件与拖拉机后轮之间的间距、路面通过角以及悬挂点的受力等参数，找到了悬挂机构的关键参数，通过优化仿真，得到了悬挂机构的最佳工作参数，仿真结果表明，设计变量DV_2、DV_3在结构受限范围内分别取其最大值和最小值，悬挂机构悬挂点受力最小。

Also the normal form and thediagram of the Hopf bifurcation are deduced with the normal form direct method.Secondly, the influences of the physical and aerodynamic parameter on the type of theHopf bifurcation are analyzed. Study shows that the "hard" structural non-linearitiesand the longer distance of the suspension point and the center of mass render theairfoil safer, whereas the "soft" ones render the airfoil more unsafe.

同样应用规范型直接法，研究得出系统颤振的Hopf分岔解的规范型以及分岔图；其次，研究了系统结构和气动参数对Hopf分岔类型的影响，结果表明，表明具有&硬&弹簧性质的结构及增大悬挂点与质心的距离都有助于提高安全性，而应该避免应用&软&弹簧性质的结构。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
